4 Claims.

The present invention relates to an apparatus for removing burrs. from welded rod ends, rings or loops.

One object of the invention is to providean `if apparatus Which will remove the burrs from the entire circumference of the metal Without the necessity of taking the metal out of the apparatus and turning it around.

Another object is to provide a holding and clamping device on the apparatus for relieving the operator from holding the b-urr against the cutter, and permits him to rotate the metal in a more uniform manner, resulting in a more uniform removal of the burr.

Other objects and advantages will become apparent as the description proceeds, in which:

Figure l is a vertical sectional elevation of the apparatus of the present invention;

Figure 2 is a sectional elevation at right angles to Figure 1;

Figure 3 is an enlarged detailed View showing the jaws, cutters, metal supporting member and the means for rotatably holding the metal on the supporting member; and,

Figure 4 is a top plan of the construction shown in Figure 3.

In the drawings, the numeral 2 represents a welded steel frame for supporting and housing the operating mechanism of the present inven- 30 tion.

Extending into said frame from a motor is a shaft 3 adapted for eccentric movement. Suitably journaled upon said shaft is an arm 4 to which is pivotally connected the reciprocating jaw member 5. A reciprocating jaw member 5 is provided with a laterally extending arm 1 for pivotally connecting, for simultaneous vertical movement, said members 5 and 6.

The reciprocating member 5 is slidably supported in a bracket arm 8 secured, 'in any con.- ventional manner, to said frame 2. Adjacent the upper end of each of the members 5 and 6, there is provided a cut-out portion for receiving the cutters 9.

Mounted upon the top of said frame 2, in any conventional manner, is a rod supporting member l2, of substantial U-shaped construction and provided with a slot I4 through which bolts I5 are adapted to pass. This supporting member l2 is capable of being adjusted transversely of the vertical plane of the metal rods I6 and is provided, on the upper surface of one end, with a tapered portion Il which supports said metal rods i6 thereon.

Also mounted upon the top of said frame 2, in

any conventional manner, are guide blocks i8 and i9 having suitable openings through which is adapted to slide, transversely of the vertical plane of the metal rods, a rod holding member 20 of substantially U-shaped construction provided with an integrally formed laterally ex-` tending arm 2|. Pivotally secured to said mem ber 20, at 22, is a bell-crank 23. The bell-crank is pivotally supported on the frame at 2t and has pivotally secured, at 25, to the other arm thereof the treadle operated lever 26.

A bracket 2l is secured to said frame, in any conventional manner, and pivotally supports a bell-crank 28 on one end of which is mounted the roller 29 While the other end is slidably connected, through the pin and slot construction shown at Sli-3|, to said treadle operated lever 2. A spring 32 normally maintains the treadle 33 in the position shown by dotted lines in Figure l.

In inoperative position, the foot treadle 33 being in raised position as shown in dotted lines of Figure l, the rod holding member 2B is in its retracted position and the hingedjaw member 6 is in the dotted line position shown in Figure 3. This permits insertion of the b'urred rod or hoop I6 upon the adjustable supporting member I2, after which pressure is applied to the treadle 33 which moves the rod holding member 2i! in a direction transversely of the vertical planev of the rod or hoop I6, so as to rest upon the top of said rod or hoop and rotatively hold the same on the supporting member l2. Upon further pressure on the foot treadle 33, which results vin a further upward movement of the lever 26, the pin 30 engages the bottom of the slot 3i on said lever and causes an upward movement of the arm of the bell-crank 28; and, due to its pivotal connection on the bracket 2l, the other arm carrying the roller engages the pivotally movable jaw member 6 to force. the same inwardly in order that the cutter may engage the burred portion of said rod or hoop for removing said burred portion upon reciprocation of the jaw members 5 and 6. Such a construction requires no eiiort on the part of the operator to hold the burred portion of the rod or hoop against the cutters. It permits him to rotate the hoop, as shown in dotted lines in Figures 1 and 3, in a more uniform manner, resulting in a more uniform removal of the burr from the material without the necessity of taking the rod or hoop out of the apparatus and turning it around in order to remove the burred portion from the entire circumference of the material.

While I have shown and described a specific embodiment of the present invention, it will be seen that I do not Wish tobe limited exactly thereto, since various modications and changes may be made Without departing from the scope of the invention, as defined by the 'following claims.

I claim:

1. An apparatus for removing burrs from Welded rod endsincluding a pair of spaced o-ppositely disposed pivotally connected reciprocating members, cutters on said reciprocating members, a rod supporting member, a U-shaped mem,- ber for rotatably holding said burred Welded rod on said supporting member With the burr in the path of said cutters and means for reciprocating said cutters.

2. An apparatus for removing burrs from Welded rod ends including a pair of spaced pivotally connected reciprocating members, cutters on said reciprocating members, an adjustable rod supporting member having an inclined upper face, means for holding said burred Welded rod for rotatable movement on said inclined face of said supporting member and means for reciproeating said cutters.

3. An apparatus for removing burrs from said members.

Welded rod ends in a single operation including a pair of pivotally connected reciprocating members, cutters on said reciprocating members, a transversely adjustable rod supporting member, a U-shaped member for holding said burred welded rod for rotatable movement on said supporting member With the burr inthe path of said cutters and means for reciprocating said cutters in unison, said holding means adapted to be moved transversely of the vertical plane of said rod.

4. An apparatus for removing burrs from Welded metal in a single operation including a pair of spaced reciprocating members, cutters on said reciprocating members, one of said reciprocating members pivoted to the other reciprov HUGH WHITMAN HAYNES.
